“…Human support is commonly used in caregiver interventions online ( Guay et al, 2017 ) and can enhance adherence ( Kelders et al, 2012 ; Kampmeijer et al, 2016 ) and intervention efficacy ( Webb et al, 2010 ). Moreover, reminders ( Fry and Neff, 2009 ; Webb et al, 2010 ) and the RCT format appear (for different potential reasons) to increase adherence ( Kelders et al, 2012 ), which was also mentioned by participants in a previous study ( Stjernswärd and Hansson, 2016b ). Lack of support and feedback can be further barriers, while ease of use, prompts and personal support may facilitate the use of such interventions ( Kampmeijer et al, 2016 ), as partly illuminated in the current study.…”
